Cleaning/Removing Corrosion from Cast Aluminum Parts

How do I clean the corrosion from an aluminum motorcycle brake hub part? The part in question is cast and machined aluminum, about 8 inches in diameter, with lots of nooks and crannies. It's covered with corrosion as if were left outside for a time in a damp place like Florida (which it was).
